MITRE ATT&CK

T1059.001 PowerShell

The PDF file contains embedded JavaScript, indicated by the PDF_JAVASCRIPT and PDF_JS heuristics. The CLAMAV_DETECTION heuristic identifies it as Pdf.Exploit.Agent-36014, suggesting it exploits known PDF vulnerabilities. The embedded JavaScript file, javascript_obj0013_001.js, is flagged for obfuscation, likely to conceal its malicious payload. The lack of readable document body text prevents a more specific assessment of the lure, but the presence of obfuscated JavaScript points to an exploit attempt.
